From K-anonymity to Differential Privacy back to K -anonymity!
Résumé
The research community has left no stone unturned in devising strategies for both syntactic and semantic privacy definitions. The literature on privacy protection reveals that no privacy model is capable of incorporating growing demands of data publication (e.g., the adversarial background, needs of data publisher, constraints on underlying dataset etc.). Thus, despite the countless efforts, privacy protection remains an open issue.
